is relatively high, which significantly limits the development of the SLM. In this study, the 316L fine powder and coarse powder with a mass ratio of 80:20, 70:30 and 60:40 were mixed using a ball... preparation technology, the cost of the fine powder is relatively high, and the price is about 10 times that of the conventional powder. Therefore, from the perspective of saving raw materials......
-striking [11, 12]. Pure and highly compressible iron powder and Mo pre-alloyed powders, diffusion-alloyed powders with combinations of Cu, Ni and Mo are to date the most used materials for high... routes is promising in near net-shape capability. However, the high cost of powder manufacture is a main hurdle to the development of Ti product in automobile. There are two approaches for making PM Ti......
